[ARTICLE] Square Jaw Surgery: Facial Bone Structure and Lower-Face Balance Matter More Than the Amount of Bone Reduction

A square jaw may be a concern when the lower part of the face appears wide from the front or when the angle of the jawbone below the ear is prominent from the side. This facial shape can be influenced by various factors, including not only the size and shape of the mandible, but also the development of the masseter muscles used for chewing and the amount of fat beneath the chin. Square jaw surgery is a type of facial contouring surgery that aims to improve the contour of the lower face by adjusting the shape and width of the mandible. However, the surgical outcome is not determined simply by removing a large amount of bone. It is important to determine the appropriate extent and location of bone reduction based on each individual’s skeletal structure and overall facial proportions. In particular, excessive reduction of the mandibular angle located below the ear may result in an unnatural side profile. On the other hand, reducing only the prominent area visible from the side may not ...

"Everything about revision facial contouring surgery"


Let's talk more about revision facial contouring.


***


In the first case, the patient visited for a consultation to remove the pin after double jaw surgery.

After CT scans, surgery was planned to improve asymmetry which still remains, and reduce the cheekbone and the length reduction of the chin.


During surgery, all the pins were successfully removed, the cheekbones were reduced to match the proportion, the length of the chin tip was adjusted and the jawline was trimmed as well.

The second case is a person who visited for a lifting consultation.
The patient had a previous surgical history of the cheekbone, so we took a CT scan to check the bone condition.

All the pins for fixing the cheekbones were broken or out of place. 
On the right side, the patient still felt uncomfortable in the 45-degree cheekbones when eating.


The current condition of the bone was judged to be one of the causes of facial sagging as well as functional problems, so revision cheekbone surgery was performed.


***


The last case is where the patient decided on revision surgery since didn't feel much improvement in the side cheekbone, especially on the right side
even if she felt a 45-degree change in the cheekbone area.

On the right side, the 45-degree cheekbones were not sufficiently close attached inwards due to the design of the bone fracture line, which was wider than on the left.
The surgical plan was to partially remove a disturbing bone and re-fixate the cheekbones.


During the surgery, the empty space on the upper part of the cheekbone was large, so I compensated the cut-out bone piece changed to a transplant form.
You can see it in the picture the space is sufficiently filled and the CT results are as follows.

As you can see, successful surgery requires a harmonious combination of accurate diagnosis, an optimized surgical plan, safe surgery, and meticulous follow-up.
